Navigation install guide needed

Recommended Posts


I tried to search multiple forums but did not found a comprehensive guide that could help me to identify how to proceed with this task.

I have 2006 997 C2. No CD changer, no BOSE. I assume it has PCM 2.1.

Main+Trip button on my PCM shows this:

Sw versions 4.0

System software

Target: 05462ad1/4605


Target 05395bd1/4505

So my assumption is to make navigation work all I need is to add DVD unit and GPS sensor. I sent question to Porsche service manager I know about parts numbers but he found codes for entire kits that include master PCM units.

So could anybody confirm - do I need or do I not need to replace master PCM unit?

If not, how to determine without taking PCM unit out what part number is it and what DVD part number I need for it?

Should it be horizontal or vertical? Could anybody with access to catalog help me to identify all that? My chassis from VIN is


I found links to


but they do not work anymore. Can anybody help me please?


I found this web page


and it is helpful but again opens simple question - how to find out what do I have now? Is the only way to find out - to pull PCM unit out?

Based on my wee bit of PCM/NAV work I don't think you'll need to replace your PCM hardware. You'll need the NAV DVD unit, NAV DVD disc, possibly a PCM S/W upgrade and of course the NAV antenna, MOST (fiber optic cable) connector in order to get the NAV system into your fiber optic ring. I suspect you current PCM has a input for the antenna and any other connection required for NAV to function. You should have a 12v power connector the NAV unit located on the driver side (left) behind the plastic panel adjacent to the battery.

I've updated my PCM and NAV software plus installed a Dension Gateway so I'm somewhat (far from an expert) 'familiar' w/ the integration of another device on the 'ring. You might have to have a Porsche dealer via their PWIS activate (recognize) the NAV unit after you're done.

If your current PCM unit has buttons for 'NAV' it should be ready to go.

Good luck . . . Keep us posted on your progress.

Thanks, will do. I assume now all I need is to get DVD drive 997 642 157 00. Plus sensor and wiring.

Will try to find it somewhere.

eBay has them listed occasionally. Just be sure it's the proper one and that it contains all the periphery stuff.

I gave up and picked new kit from sunset for $2395. Pricey, not sure if was worth it.
